Same here. All my wandering problems were solved by installing adjustable LCA's and setting caster at 6 degrees.The excessive wandering in the steering is likely caused by a low caster angle. The caster should be 5-5.8 degrees to have tight steering. Mine was 3 degrees. My dealership ordered adjustable control arms so they could get mine back in the 5 degree range. They also ordered a heavier duty steering stabilizer to go a step above. These two things will get your steering very tight and enjoyable to drive.
